About Our Torch Down Roofing Service
Torch-down (modified bitumen) is one of the most reliable low-slope roofing systems available. It combines the redundancy of built-up roofing with the flexibility of a single-ply membrane. Our crews are trained in proper torch safety, obtain required city permits, and maintain fire watch protocol on every installation — critical in San Diego's fire-prone environment.
Best For
Low-slope residential sections, patio and porch covers, second-story additions, garage roofs, and small commercial applications.
Our Process
Every torch-down project includes a substrate inspection, base sheet installation, cap sheet torch-application, and detailed flashing at penetrations, walls, and drains. We pull all required permits and schedule fire watch per city code.
Warranty
Manufacturer warranties from 15–20 years plus our workmanship warranty on all seams and details.
Frequently Asked Questions
How long does torch-down roofing last?
A properly installed 2-ply modified bitumen system lasts 15–20 years; 3-ply systems can reach 25 years. Longevity depends on cap-sheet quality and detailing at penetrations.
Is torch-down safe near living spaces?
Yes when installed with proper safety protocol. Our crews maintain fire watch, use fire-resistant blankets on adjacent materials, and pull required permits — never a corner-cut torch job.
